Functional Description
Display Display Mode static display organized into bits stores data transmitted from external device HT16511 through serial interface. contents directly mapped contents driver. Data accessed through data setting, address setting display control commands. assigned addresses 8-bit unit follows:
Dimming Control HT16511 provides 8-step dimmer function display controlling 3-bit binary command code. full pulse width grid signal divides into uniform sections (pulse width modulation) technology. uniform sections available form steps dimmer 3-bit binary code. 8-step dimmer includes 1/16, 2/16, 4/16, 10/16, 11/16, 12/16, 13/16 14/16. 1/16 pulse width indicates minimum lightness. 14/16 pulse width represents maximum lightness (Refer display control command). Matrix Key-Input Data Storage matrix scans series states each level strobe signal (S1/K1~S12/K12) output HT16511. strobe signal outputs time-multiplexed signals from S1/K1~S12/K12. states inputs K0~K3 sampled strobe signal S1/K1~S12/K12 latched into register.
Note:
Only lower bits addresses assigned SEG17 through SEG20 valid, higher bits ignored.
